I get

H2:~% port installed depends webkit-gtk
The following ports are currently installed:
  webkit-gtk @2.0.4_1+video (active)

Does this mean that I have no other ports that depend on webkit-gtk?
Maybe I installed a port X that needed webkit-gtk at the time of installation, but an upgraded version of X no longer needs webkit-gtk.
I am very about what I install, and normally only install programs that I actually need and use.

Thanks for the explanation.
